Air filters play a vital role in your car's performance. Cabin air filters help keep the air inside your car's cabin clean and free of harmful particles such as pollen, dust, dirt, and other contaminants. Similarly, engine air filters keep the air entering your engine's cylinders free of debris that can cause damage to the internal components.
That's why it's important to replace your cabin and engine air filters regularly. How often you should complete this maintenance task depends on a few factors such as the type of filter you have, the climate you live in, and how often you drive.
If you frequently drive through dusty roads or off-road trails, for example, your filters will need to be changed more often. In general, it is recommended to replace both filters every 15,000 miles or once a year — whichever comes first — but it is always best to refer to your car's owner's manual for the exact recommendations.
